Superforms is a SvelteKit form library providing comprehensive server and client-side form validation with support for many validation libraries like Zod, Valibot, Joi, and Yup. It offers a minimal, fully typed API for handling form data, errors, nested data, multiple forms, and client-side validation.

Use cases

• validate sveltekit forms on server and client
• handle multiple forms on one page in sveltekit
• post nested data structures from a sveltekit form
• prevent losing unsaved form data when navigating away
• add realtime client-side validation to svelte forms
• coerce formdata into typed values including files and arrays
• build single-page app forms in sveltekit

When to choose

• you are building forms in a SvelteKit project and want typed, validated form data
• you want to use an existing validation library like Zod or Valibot with consistent error handling
• you need nested data, file uploads, or multiple forms with a minimal API

When to avoid

• you are not using SvelteKit or Svelte
• you need a framework-agnostic form solution for React or Vue
• you only need simple unvalidated HTML forms with no extra features
